Function:    MouseBrowse()

               this function is a partial replacement of the
               MemoEdit() function as it will only support
               the browsing of Memos. But the browsing is,
               next to normal editing keys, also possible by
               use of the Mouse. Browsing Memos is used in quite
               some situations, and supporting the mouse in those
               operations is supposedly a welcome addition. Editing,
               on the other hand, is hardly easier with a Mouse.

  Syntax:      MouseBrowse(nTop,nLeft,nBottom,nRight,cMemo[,bTrap])

  Arguments:   The four first arguments define the Memo's position
               on the screen, the memo is scrolled in and out of that window.
               cMemo is the Memo variable you wish to browse.
               bTrap is an optionnal trap function, see MouseTrap for more
               information on mousetraps.

  Returns:     Nothing.

  Usage:       See the DEMO programs that have been supplied with
               the Expand library for some detailed examples on how to
               use this function.
